The most significant and possibly most expensive failures related to a new release occurred in 2012, when Knight Capital Group, a global financial services firm, lost $440 million, owing to a glitch in its servers during the release process, and, in 2013, when an upgrade failure at Goldman Sachs sent orders accidentally, resulting in the loss of what was thought to have been millions of dollars. DevOps allows a set of practices that can reduce potentially expensive errors.
When we think of DevOps, we must think of a movement formed to change how an entire company works together. The goal is to build a set of practices that can be used to reduce impediments to communication across different departments in the company. To be successful, DevOps should be promoted at the highest level of the company and accepted by each of its departments.
